Answer:

Skeletal muscles are a type of muscular tissue.

Explanation:

All types of movements in our body are due to the muscular tissue. This tissue constitutes the muscles, which are made up of long, cylindrical, fiber like cells  called muscle fibers. The muscle fibers contain the myofibrils in the cytoplasm called sarcoplasm.

On the basis of their structure and function, muscular tissue is of three types:

1. Skeletal muscle

2. Smooth muscle

3. Cardiac muscle

Skeletal muscle: It is also referred as striated or striped muscle. These are found attached to the all the bones, hence called skeletal muscle. They are voluntary in their nature which means they are under the control of our will power. These skeletal muscle provides the force for locomotion and all other voluntary movements of the body. These muscle undergo tiredness called fatigue and need rest.

scoundrel [369]

Answer:

The fraction of the offspring that will show the phenotype produced by the recessive c allele is 1024/4096 = 0.25 A-BbccDdE-Ff = 25%

Explanation:

You can calculate the fraction of the offspring that will show the phenotype produced by the recessive c allele by making the punnet square for each gene and then multipling the phenotypic proportions, like this:

Cross) AAbbCcDDEeff     x      AaBBCcddEEFF

Cross For each gene by separately:

  • Parental )        AA    x    Aa

       Gametes)  A    A         A    a

        F1)             2/4 AA  

                          2/4 Aa

  • Parental )        bb    x    BB

         Gametes)  b    b         B   b

          F1)                   4/4 Bb

  • Parental )        Cc    x    Cc

        Gametes)  C    c         C    c

         F1)             1/4 CC

                           2/4 Cc

                            1/4 cc

  • Parental )        DD    x    dd

       Gametes)  D    D          d    d

        F1)             4/4 Dd

  • Parental )        Ee    x    EE

        Gametes)     E     e      E     E

         F1)             2/4 Ee

                           2/4 EE

  • Parental )        ff    x    FF

         Gametes)     f     f      F     F

          F1)             4/4 Ff

So, fraction of the offspring that will show the phenotype produced by the recessive c allele is:

4/4 A-  x  4/4 Bb   x   1/4 cc   x   4/4 Dd   x  4/4 E-   x   4/4 Ff =  

1024/4096 = 0.25 A-BbccDdE-Ff =25%

In phase-contrast microscopy, the differences in refractive indices between organisms and their environments are utilized for be
mina [271]

Answer:

True

Explanation:

In  phase-contrast objective and a phase contrast optical systems is equipped with Light microscope  .

Phase contrast microscope is used to differentiate unstained structures in a cell  that differ in refractive indices and thickness. Thus it is usefull for examining  living unstained organisms.

Light that passed through materials of different refractive index and/or thickness will undergo a change in Phase. The difference in phase or wave front irregularities cause variation in brightness of the structures.

Hoping this might help!!!
